Title: Single crystallization for non-single crystalline semiconductor layer
Inventor: SAKURAI JIYUNJI
IPC: H01L21/208
Filed: 1981-01-30
Abstract: PURPOSE:To efficiently single-crystallize a non-signal crystalline layer by partly superposing a region to be scanned on the previously scanned region after the second scanning, thereby increasing the area of the single crystal obtained by the first scanning. CONSTITUTION:When a laser beam 15 is scanned, a substrate is solidified from the  center upon movement of the beam 15. A line 17 represents a boundary line between a  solid phase and a liquid phase so that the right side is solid and the left side is liquid.  Since the center grows in accordance with the planar orientation of the crystal of the  substrate contacted via a hole 3, it becomes a single crystal. Then, a rectangular laser  beam 15' having an intensity gradually increasing from the region scanned by the first  scanning an oblique intensity distribution abruptly decreasing at the opposite side is  scanned as the second scanning from the start point of a hole 3 over a polycrystal 16b  to be superposed on a single crystalline layer 16. Since the substrate is solidified, as  shown by a boundary line 17', from the previously scanned region side in this manner, the crystal is grown in accordance with both orientations of the single crystal layer 16,  a single crystalline layer 16' is thus formed, and the polycrystalline layer is formed at  the lower side.

Title: Tin oxide semiconductor for gas sensor and manufacture thereof
Inventor: NAKANOUCHI YUKIO
IPC: G01N27/12
Filed: 1988-01-25
Abstract: PURPOSE:To obtain a gas sensor element which has a sufficient gas sensitivity and disperses with a catalyst setting process and which can be miniaturized and integrated, by evaporating simultaneously SnO2 and one or two or more of Pt, Pd and Ir. CONSTITUTION:SnO2 and one or two or more of Pt, Pd and Ir are evaporated simultaneously by a sputtering method or a vacuum heating evaporation method, and a catalyst metal is dispersed finely in SnO2, so as to form a thin film of a two-phase structure of the catalyst metal and a tin oxide. Thereby a semiconductor having a catalysis of high activity is obtained. The Pd, Pt and Ir to be alloyed dispersely are selected according to the kind of a gas to be detected, and when Pd is put in, for instance, the semiconductor shows a large resistance variation to a methane gas. When Pd, Pt and Ir are used together, it becomes sensitive to gases of a wide range. However, the properties of the film obtained become metallic as the rates of these metals increase, and it turns to show no resistance variation to the gases of various kinds. Therefore the total weight concentration of these metals is set to be 0.1-20%.

CONSTITUTION:A frequency divider section 200 divides a clock signal ba having a prescribed period into two, and outputs a frequency divider clock signal bc having a period twice the period of the clock signal ba. A counter section 300 counts the frequency division clock signal bc outputted from the frequency divider section 200 and outputs a count bd. An output discrimination section 400 discriminates the count of a frequency division clock signal bc outputted from the frequency divider section 200 and of the clock signal ba of the predetermined pulse number with the count bd outputted from the counter section 300 and outputs an output signal be. Thus, up to a clock signal having a period being a half the count capability of the counter section is able to be counted.

Title: Method and apparatus for measuring tension breaking stress
Inventor: YODA NOBORU
IPC: G01N3/08
Filed: 1989-01-21
Abstract: PURPOSE:To enable measurement of a tension breaking stress near right below a solidification point accurately and handily by removing a part of a mold when metal within a mold reaches a specified temperature right below the solidification point to apply an volumetric force by a centrifugal force to metal in place. CONSTITUTION:Temperature within a chamber 1 is controlled to a specified temperature right below a solidification point of a sample material and a mold 7 wherein molten metal is injected into an end of an arm 3 provided in the chamber 1. Then, when a rotating shaft 2 is accelerated with a motor 8 to reach a specified rotational speed, the arm 4 performs a uniform circular motion at a position where a centrifugal acceleration balances with a dynamic acceleration maintaining a fixed angle with the rotating shaft 2 with a distance from an arm pin 4 to the mold 7 as rotation radius. Then, after the rotational speed of the arm 3 reaches a specified value, the mold is separated to impart a volumetric force to the sample material at the part from which the mold 7 is separated away by a centrifugal force. The volumetric force is applied to a portion with the smallest sectional area of the part from which the mold 7 is removed to break it and the sample material is broken. Thus, a tension stress is calculated from a mass of the sample material broken and the centrifugal acceleration at that time.

Title: Range limit type optical sensor
Inventor: MATSUDA HIROSHI
IPC: G01J9/00
Filed: 1985-01-25
Abstract: PURPOSE:To prevent the trouble in the detection of phase difference due to the timewise change in the bias of an amplifying part, by converting the signal emitted from a light emitting part to a burst wave and connecting a large capacity condenser to a bias resistor. CONSTITUTION:At first, the signal emitted from a light emitting part is received by a light receiving part and inputted to an amplifying part through a preampli fier and a mixer. At this time, the bias point of the operational amplifier OP of the amplifying part is ready to vary with the elapse of time. However, be cause large capacity condensers C2, C3 are connected to the resistor mounted in the operational operator OP determining the bias point, the variation of the bias point becomes gentle by the time constant determined by the resistor in the operational amplifier OP and the condensers C2, C3. If the capacities of the condensers C2, C3 are set so as to make the time constant sufficiently larger than the oscillation cycle T of a burst wave, the bias point of the opera tional amplifier OP takes almost constant value during the emission of light from the light emitting part and, therefore, no variation is generated in the output in the amplifying part.
